s CPU CORE
1. Memory Space
The microcontrollers of the MB89630R series offer 64 Kbytes of memory for storing all of I/O, data, and program
areas. The I/O area is located at the lowest address. The data area is provided immediately above the I/O area.
The data area can be divided into register, stack, and direct areas according to the application. The program
area is located at exactly the opposite end of I/O area, that is, near the highest address. Provide the tables of
interrupt reset vectors and vector call instructions toward the highest address within the program area. The
memory space of the MB89630R series is structured as illustrated below.
Memory space
*1: The ROM area is an external area depending on the mode.
The internal ROM cannot be used on the MB89T635R and MB89T637R.
*2: Addresses 8000H to 8006H for the MB89P637 and MB89W637 comprise an option area, do not use
this area for the MB89PV630 and MB89637R.
